'An object ofthe `present invention is to profvide a valveofthev foregoing character having an operating handle' which maybe Vreadily ma- Another object of the `invention valve secured thereto which is `provided with aV carrying handle tate discharging the contents of the container while carrying the same.'l

Another object is toprov-ide a valve of the foregoing character having means for effecting latching of theoperating handle in valve operating position in a simple and expeditious manner. j

Another object is to provide a valve `of the foregoing character which is simple and sturdy in construction and comprises a minimum nurnber of parts which are readily manufactured and assembled. 1 I f5;- 'k

A further object consists in the construction and arrangement of parts, whereby the foregoing objects may be accomplishe l Other and further objects of the invention will (Creez- 3) `more particularlyto valves for portable containl is toprovide' I' a high pressureuid media container having a y and a valve operating handle operatively associated'with each other to facilibe obvious upon an kunderstandingof the illustrative embodiment aboutto be described, or will be indicatedvin the appended claims, and various advantages not referred to herein will occur to one skilled in' the art upon employment of the inventionin practice. l yA preferred embodiment of the invention has been chosenfor purposes of illustration and description kand is shown in the accompanying drawing, forming a part of the specification, wherein: y f l s Figure l'is a sectional view of a valve attached'V to a portable high pressure fluid media container (partly shown), illustrating an embodiment of the invention.

Figure 2`jis a fragmentary sectional view of a modified latching arrangement.

Referring more particularly to Figure 1 of lthe drawing,there is shown a container, `such as a portable cylinder bon dioxide adapted to be used for're extin guishing vpurposes lor the like.` Thecylinder is The valve comprises a valveibodyll having a ls adapted,totey il adapted to contain `high pressure fluid media, for example, liquified carl of' the passage shaped portion I5 and preferably communicates.

' one end thereof pivotally threa'dedly secured into opening orV outlet of the cylinder. The valve body'is formedwith a passage I8 extending therethrough. One end I8 extends' through the plug- I1 which is secured to the 5 and extends into the cylwith a' syphon tube plug-shaped portion I inder. The other end of the'passage` IB comv municates with an outlet I9 to which a suitable shield or horn -(notshown) may be connected for effecting discharge of the iluid media from ,the cylinder.l .v-

A valve chamber 20 is provided in the passage I6 between the respective ends thereof-which lis formed with a valve seat 2| upon which'a valve member ordisc 22 is` adapted to be l means of a suitable spring or the like. The valve member one end 4of a suitable pin or fsrod 26 slidably 'mounted in the valve body and extending through a suitable packing or gasket 2B. VThe other end of the pin 25 extends outwardly of the valve body and is adapted to be engaged by an 'operating handle 21 or thelike, described hereinafter.,`

In order to readily facilitate lifting and carrying the cylinder -to-which the valvel is secured, an elongated carrying handle 29 is provided which has one end thereof attached tothe valve body, `and .extending outwardly thereof. vhandle 29 may be pvotally mounted between a pairoi` lugs or ears 30 (one shown) formed with the valve body by means ofa pinl supported by the lugs 30. With this arrangement the handlef29 may be swung downwardly against the cylinder when .not in use and may be swung upwardly when the cylinder is to be liftedorcarried. Intermediate its ends, the handle 29 is provided with an aperture or recess 32l formed withk an undercut or shoulder 34, thefunction of ywhich will be described hereinafter. f

The operating handle 21 referred to herein has body.v This may be accomplished by mounting the handle 21 on a pin supported by a pair of lugs or ears 3.8 (one shown) formed with the valve body above the lugs or ears 3U. Adjacent its pivotally mounted end, the handle 21 is provvided with a cam portion`31, or the like, adapted to vengage and` move the slidable pin or rod 25 to leffect unseating of the valve member 22.

The operating handle 2.1 extends outwardly of the valve body and is positioned above jacent the carrying handle 2,9, as illustrated herein, so that it may be readi1y-`pressed downwardly toward the carrying handle to operate thevalve. i

seated by 22 is adapted tobe unseated byv The.

attached to the`valve and ad- Vcarrying handle 29 and In accordance with the invention, it is desired to lock the operating handle in valve operating position to maintain the valve member 22 unseated. 'I'his may be accomplished by a suitable latching device associated with the handles. For example. the operating handle may havea latching member 40 pivotally supported thereon which extends'through an aperture or recess-4i formed in the handle 21. The lower end of the latchingmember 40 is formed with aglatching projection 42 adapted to extend into the aperture 32 of the Y adapted to engage the undercut Aor shoulder 34 (as shown in broken lines) to thereby link the operating handle 21 in latched relation to the carrying handle 29 in the downwardly pressed operating position of the operating handle.

A spring 45, under tension, having one end connected to the latchin'g member above its pivot and having its other end connected to the operating handle, may be provided for urging the projection 42 into engagement withl the undercut or shoulder 34. The upper end oi' the latching member 40, projects above the operatinghandle 21 and is provided with a knurled portion 46 adapted to be engaged and pushed by the thumb of the hand'grasping the handles to thereby eilect disengagement of the latch.

In Figure 2 a modiiied latching arrangement is illustrated which comprises a substantially horizontal lug, ear, or extension 50 formed with the As various changes may be made in the form, construction and arrangement of the parts herein, without departing `from the spirit and scope of the invention and without sacricing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in any limiting sense.

It is also to be understood that the following claims are intended to cover all the generic and specic features of the invention herein described, and allstatements of the scope of the invention which, as a matter be said to fall therebetween.

I claim: t t A u 1. A valve construction comprising a valve body having a passage extending therethrough and having a valve seat in said passage; a valve member for said valve seal?? an axially slidable operating stem mounted in said valve body for eii'ecting unseating of said valve member and provided with an exposed end; said valve body valve body and having an aperture 32' extending therethrough which is provided with an undercut or shoulder 34' adapted to be engaged by the latching projection 42 of the latching member 40.l

In operation, handle 29 is grasped by the fingers of one hand and pressure is exerted on the upper side of the operating handle 21 by the palm of the hand to move the operating handledownwardly toward the carrying handle. As this is being done the lower end. of the latching member moves downwardlyin the aperture 32 (Figure 1) or 32' (Figure A2) and the latching projection 42 thereon is urged into engagement with the undercut 34 (Figure 1) or 34 (Figure 2) by the action of the spring 45. This eiects latching the operating handle and maintains it in a position to cause the valve member 22 to be held unseated to permit the fluid media to be discharged from the cylinder.

When it is desired to permit the valve member 22 to reseat and stop the discharge of the iuid media, the portion 46 is pushed towardthe valve body in opposition to the spring by the thumb of the hand grasping the handles 21 and 29. Disengagement` of the latch is thus eected, permitting the operating handle to be raised to its initial position.

From the foregoing description it will be seen that the present invention provides animproved valve for portable containers of high pressure uid media or the like. With the arrangement illustrated herein, the container and the valve constitute a portable self-contained unit which can be readily lifted or carried and the valve can be readily operated by an ordinary full hand squeezing action, while in the carrying position, tp distribute the iluid medium over wide areas. This leaves the 'other hand freeto manipulate the discharge horn or, while the uid discharge is stopped, to be employed for other purposes. The valve is rugged in construction and can readily withstand any rough usage to which it may be subjected.
